"Since the energy per fission from Pu-239 and U-235
is about the same, the theoretical fuel value of fissile Pu is $5600 per
gram. Reactor grade Pu also contains non-fissile isotopes, reducing its
value to about $4400 per gram."

"The price of weapons-grade Plutonium surged $200
over the past three weeks to an all-time high of just over $4,000 per gram,
according to an international survey. And with the start of terrorist season
just around the corner, prices are not expected to drop anytime soon."

Plutonium is an artificial,radioactive, metallic and toxic chemical element.
It has only two main uses: a source of nuclear energy and a source of nuclear
weaponry. It is very sought after by terrorists and various developing nations
for their plans of nuclear arms production. The “Fat Man” bomb dropped in Nagasaki,
Japan in 1945 that killed 40,000 people instantly and killed thousands more
in the following years from fallout, consisted of a plutonium-239 core.

In 2008, the price of plutonium has drastically increased since the 1990s, but was relatively expensive during the Cold War. Over the last three weeks, the price of weapon-grade plutonium has surged 200 dollars to 4000 dollars per gram, or even more for rarer grades. By these estimates, the mass plutonium needed for the average nuclear bomb, or about 6 kg goes for about thirty-one million dollars.

So one day if your inner-terrorist decides to come out, remember this very important
fact: plutonium is extremely expensive. Its super high price of several thousands
of dollars per gram means that in most cases a single terrorist would not be
able to afford it. But a terrorist organization and a national government in
today's world could easily afford it.
